I found them very helpful as well when I contacted them recently about my step-daughter's change of name. I sent an email to the embassy and within an hour, a lady there had tried to contact me by phone and had left a message for me to call her back. I did call her back when I returned from my lunch break and she was extremely friendly and helpful.
If you sent an email to the British embassy in Phils you'd be lucky if they replied to you within a week and if you actually tried to phone them, I'm sure it would take quite a few attempts before you would get through, if at all.
